CVE-2025-55044 is a Cross-Site Request Forgery (CSRF) vulnerability affecting MuraCMS versions through 10.1.10. The vulnerability resides in the cTrash.restore function, which handles restoring deleted content from the trash. This function lacks proper CSRF token validation, allowing attackers to craft malicious web pages that, when visited by an authenticated MuraCMS administrator, cause the administrator's browser to unknowingly submit a forged request. This request restores deleted content to arbitrary parent locations specified by the attacker via the parentid parameter. Because the attacker can control the restoration location, they can place previously deleted malicious content back into the website structure, expose sensitive or confidential documents by restoring them to public areas, or reintroduce outdated content that was removed for security or compliance reasons. The attack requires the victim to be an authenticated administrator and to visit a malicious webpage, but no additional privileges or user interaction beyond page visit is needed. The vulnerability impacts confidentiality, integrity, and availability of the affected CMS content and site structure. Although no public exploits are known, the high CVSS score of 8.8 indicates a serious risk. The root cause is the absence of CSRF token validation in a critical content management function, a classic CWE-352 weakness. This vulnerability highlights the importance of implementing anti-CSRF protections on all state-changing operations in web applications, especially those accessible to privileged users.

The impact of CVE-2025-55044 on organizations using MuraCMS is significant. Successful exploitation allows attackers to restore deleted content without authorization, potentially reintroducing malicious code, outdated or vulnerable content, or sensitive documents into the website. This can lead to website defacement, data leakage, or compromise of the website’s integrity and trustworthiness. Restored malicious content could be used to launch further attacks against site visitors or internal users. Unauthorized restoration of sensitive documents may result in compliance violations or data breaches. Manipulation of the website navigation or content structure can disrupt normal operations and damage brand reputation. Since the attack requires an authenticated administrator to visit a malicious page, organizations with many administrators or less stringent browsing policies are at higher risk. The vulnerability affects confidentiality, integrity, and availability of web content, potentially impacting business continuity and regulatory compliance. Although no known exploits are reported, the ease of exploitation via social engineering and the high privileges required make this a critical risk for affected MuraCMS deployments worldwide.

To mitigate CVE-2025-55044, organizations should: 1) Immediately apply any available patches or updates from MuraCMS once released. 2) If patches are not yet available, implement web application firewall (WAF) rules to detect and block suspicious POST requests to the cTrash.restore endpoint, especially those lacking valid CSRF tokens or originating from external referrers. 3) Enforce strict administrator browsing policies to avoid visiting untrusted or unknown websites while logged into MuraCMS. 4) Implement or verify the presence of anti-CSRF tokens on all state-changing operations, including content restoration functions, to prevent forged requests. 5) Conduct security awareness training for administrators emphasizing the risks of CSRF and safe browsing habits. 6) Monitor logs for unusual content restoration activities or unexpected changes in website structure. 7) Review and restrict administrator privileges to the minimum necessary to reduce the attack surface. 8) Consider isolating administrative interfaces behind VPNs or IP allowlists to reduce exposure. These targeted measures go beyond generic advice by focusing on the specific vulnerable function and attack vector.
